kernel: null pointer dereference in drivers/net/wireless/intel/iwlwifi/pcie/trans.c
drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
A flaw was found in the Linux kernel. A check was not done on the alloc_workqueue return value of the iwl_trans_pcie_alloc function potentially leading to a NULL pointer dereference. This error condition could lead to a denial of service. The highest threat from this vulnerability is to system availability.
Statement: This issue is rated as having Low impact because of the preconditions needed to trigger the error/resource cleanup code path (system-wide out-of-memory condition, high privileges or physical access). The attacker would have to be
